The term "dose pack" typically or commonly refers to Medrol dospak. But other steroids also come in that form as well. The dospak helps the patient taper off properly with each day marked clearly, so no errors occur.

A dose pack is a blister carded way to deliver a drug to the patient instead of loose pills in a bottle. (many OTC drugs are now blister packed this way.)

Z-pak is an RX antibiotic in the same format for example.

But most often dose pack refers to Medrol (methylprednisolone)
which is a steroid. Prednisone also comes this way but less commonly used.
